PETROLEUM-BURNER.

SPECIFICATION forming part of Letters Patent No. 398,352, dated February 19, 1889. I Application filed November 21, 1888. Serial No. 291,455. (No model) To all whom it may concern.-

Be it known that we, l naoniok'll. SMITH and JOHN NV. \VRIGHT, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Petroleum- Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

I0 Ourinvention relates to an lIYIPI'OX'BlIlGIlt in petroleum-burners, and more particularly to a retort with attached burners, which may be placed in a stove, range, or boiler-furnace to furnish heat for cooking, heating water, or other similar uses.

The object of our invention is to provide a simple and removable gaseous-fuel generator which may be readily inserted within the firepot or combustion-chamber of a stove, range,

or furnace, and by proper connections with a source of oil-supply be adapted to generate.

a gaseous fuel from crude petroleum, refined coal-oil, or any other suitable carbonaceous liquid.

A further object is to provide the vaporgenerating chamber or retort of the petroleunr burner with means for its ready eleansingon the interior surface when necessary.

A further object is to so construct the in- 3o terior of the retort or vapor-generating chamber that the influx of oil or carbon liquid fed into the retort will be deflected from the upper surface of said retort when the burner is cold and the operation of starting a gaseous 3 5 flame is about to be commenced.

A further object is to provide the vaporgenerating retort with integral depending vapor-discharge pipes, which connect the retort With the gaseous fuel-burners, thus prevent- 4o ing leakage from the retort when in a heated condition.

lVith these objects in view our invention consists in certain features of construction and combinations of parts, which will be hereinafter described, and pointed out in the claims.

Referring to the drawings making apart of this specification, Figure 1 is a side elevation in section, taken on center-linelongitudinally through the generator-chamber and integral burner-pipes, the burners and oil-feed pipes being shown in perspective: Fig. 2 is a bot tom plan view of the vapor-gencrating (fillftlll? her and. attached parts. l ig. 3 is a transverse section,in elevatioinotlhe retort and attached parts, taken on the line .1 1!, Fig. .1. Fig. 4 is an enlarged plan view of the bottom of one of the burners.

A represents the retort or vapor-generator chamber. This is preferably made of east metal in two pieces, B (l, which are flanged at a to permit them to be detachably secured together by the screw-bolts a, and it is evident that when the portionsB C are separated the chambers formed in them will be exposed and access had thereto through their open ends. The faces of the flanges (t are rendered true and at right angles to the shell or body of each chamber, so that the joint plate or diaphragm E, when introduced between the flanges a, will coincide with their general surface and effect a tight joint, it being un' derstood that the diaphragm-plate E is perforated near its edge at spaced intervals to register with the bolt-holes in the flanges a, and thus permit the screw-bolts a to be insert-ed and adjusted to hold the two portions 13 C of the vapor-generator together.

The joint-piece E is preferably made of copper sheet metal of any desired thickness; but other material may be employed that is suitable to afford a tight joint, withstand the action of heat, and permit the connection to be sexered without injury to the joint material.

Near the flanges a of the two retort sections or chambers B G, upon the lower surface of the same, the oil-feeding pipes H H are rigidly secured. These may be separable or be formed integralthat is to say, the por- 9o tions shown may be so constructed. These depend from the bottom of the generator-chambers B C, and at their lower ends, 0 o, are connected to extensions of the pipes, (not shown,) which latter may be projected to any suitable distance and attached to a proper source of oil-supply, which will supply'the retort generating chamber with graduated amount of carbon liquid under pressure of gravity, or any other proper manner to insure a regular feed of oil into the retort A.

At a suitable point on the lower surface of Lil and on these ends are afiixed the burners P,

so secured 'that their top portions will be located beneath the tubular orifices 1), formed in the separated chambers B C of the retort A, as shown in Fig. 1.

Both of the burners P are provided with dependingflash-pans i, that from their posi-' tion will-be adapted to catch oil or other carbon liquid fed through the pipes G and bodies of the burners P when the device is to be put into use.

It should be stated that the burners P may be of any well known and approved form of Bunsen burner, which is capable of receiving carbon-vapor generated in the retort A, and by mixture of the same in proper volume with atmospheric air afford upon ignition of the mixed gaseous fuel a blue intensely hot smokeless fiame. The style of burner P represented is well adapted for the purpose, and consists of a vapor-chamber, n, on the upper surface of whichis mounted the mixing-chamber 71..

The gauze diaphragm 7b (see Fig. t) is secured to the lower surface of this chamber 72, and an air -pip e, p, is centrally projected through the vapor-chamber n to enter the mixing-chamber h along with jets of carbonvapor, also introduced under pressure from the retort A.

The mixed air and carbon vapor issues from the apex of the mixing-chamber h, and upon ignition burns with intense heat and no smoke. The blue flames from the acro-carbon-fuel combustion effected in the burners P strike against the lower surface of the chambers B C of the retort A, and thence upward around the retort-body and through the orifices or tubes D. Such flame as enters the tubes 1) is spread by the cap-pieces (I, so as to direct the heat-currents laterally.

Upon each side of the diaphragm plate or joint E the deflector-plates f are attached. These are projected horizontally over the inlet-orifices of the oil-feed pipes H, and serve to direct the oil or other carbon liquid over the bottom wallsof the chambers B C toward the orifices c, where the pipes G intersect the retort A to convey the oil down them to the flash-pans t.

It is mainly intended to employ the gaseousfuel-generatin g device as ameans of furnishi i l i 1 1 ing fuel for heating purposes to a stove or range, and to this end the retort A and its burners are located within the fire-chamber of such a cooking stove or range, so that the heat evolved in the combustion of the gaseous fuel will first envelop the retort-surface and then spread to the top plate of the stove or range in an obvious manner, heating the same or any vessel and contents thereof placed to receive such heat. v

In operation, the retort being supplied with oil in graduated volume, the inducted carbon fluid spreads over the floor of the retortchambers B (J in a thin sheet and flows down the pipes G into the flash-pans z". The oil being ignited in these pans creates sufficient heat to vaporize the oil in the retort and produce a pressure of carbon vapor therein, which is fed to the burners P, and these, mixing with the inducted atmospheric air, furnish the heat-currents for cooking or other purposes, as has been previously mentioned.

Having fully described our invention and its mannerof operation and demonstrated its utility, what we claim as new, and desire to secure by Letters Patent, is

1. The combination, with a retort having two joined chambers and a diaphragm-wall provided with two deflector-plates, as shown, of two curved depending oil and vapor conveying pipes, two aero-carbon-vapor burners,

and two oil-supply pipes, substantially as set forth.

2. In an aero-carbon. gaseous-fuel generator, the combination, with a'retort composed of two chambers having open ends which abut against a joint-wall that is interposed between them, of two integral depending pipes and acre-carbon-vapor burners that are affixed to the lower ends of these pipes, sub stantially as set forth.

3. In an acre-carbon gaseous-fuel generator, the combination, with two chambers having open ends, a diaphragm-plate that is a jointwall between these chambers, and bolts toconnect the chambers detachably, of two oilfeed pipes that are formed on the lower walls of the chambers, two depending curved oil and vapor conveying pipes, and two aero carbon-vapor burners, substantially as set forth. In testimony whereof we al'fix our signatures in presence of two witnesses.
